| All Calcium requests will be reported with a corrected calcium value.
Corrected Calcium = Calcium + 0.012*(39.9 - Albumin) Prolonged stasis during venepuncture and haemolysis will give false high values For baseline level, patient should be fasted for 12 hours and seated for 20 minutes prior to specimen collection. | |
